Reaction Steps

NaH (60% dispersion in oil, 42 mg, 1.1 mmol) was added to a solution of tert-butyl 7-bromo-3,3-dimethyl-3,4-dihydro-1H-pyrido[3,4-b]indole-2(9H)-carboxylate (200 mg, 0.528 mmol) in DMF (10 mL) under N2, and the resulting suspension was stirred at 25° C. for 30 min. MeI (0.05 mL, 0.8 mmol) was added to the suspension, and the resulting suspension was stirred at 25° C. for 1 h. H2O was added, and the resulting solid was collected by filtration. Flash chromatography (silica gel, hexanes/(1:1 EtOAc/hexanes), 100:0 to 0:100) afforded the title compound (145 mg, 70%) as a white solid: 1H NMR (300 MHz, CDCl3) δ 7.43 (d, J=1.5 Hz, 1H), 7.30 (d, J=8.3 Hz, 1H), 7.18 (dd, J=8.3, 1.5 Hz, 1H), 4.62 (s, 2H), 3.61 (s, 3H), 2.77 (s, 2H), 1.52 (s, 6H), 1.49 (s, 9H).
